hi guys, finally got my self some star san and bloody hell does it not half foam up. my question is after soaking out my demi john wit the stuff and emptying it out the inside is still covered with bubbles and foam. now as its a no rinse sanatiser i dont wanna rinse it out so is it ok to siphon my wort directly on top of the bubbles ? is this safe for the beer ? cheers guys for any advice
